Versions 1.15.0 to 1.15.15, 1.16.0 to 1.16.8, and 1.17.0 to 1.17.2, are vulnerable when using Wireguard transparent encryption in a Cilium cluster, packets that originate from a terminating endpoint can leave the source node without encryption due to a race condition in how traffic is processed by Cilium. This issue has been patched in versions 1.15.16, 1.16.9, and 1.17.3. There are no workarounds available for this issue.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cilium/cilium","events":[{"introduced":"c9723a8df3cfa336da1f8457a864105d8349acfe"},{"fixed":"a0ee30f5ee96eaf4766453e0cae7759a6965b90d"},{"introduced":"82999990bc954699cf24853ef9747d9166ee24c8"},{"fixed":"bf7387b2b6aed80d9c8e4c04f8fc7dd6040ed93d"},{"introduced":"c2bbf787eab9b7f728fcc861904d9bcf17e4ba9b"},{"fixed":"3993bd066abcf2d493f38cbeeb104174b7ef1ed0"}],"database_specific":{"cpe":"cpe:2.3:a:cilium:cilium:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"1.13.0"},{"fixed":"1.15.16"},{"introduced":"1.16.0"},{"fixed":"1.16.9"},{"introduced":"1.17.0"},{"fixed":"1.17.3"}],"source":"CPE_RANGE"}}],"versions":["v1.17.2","1.17.2","v1.16.8","1.16.8","v1.16.7","1.16.7","v1.17.1","1.17.1","v1.17.0","1.17.0","v1.16.6","1.16.6","v1.16.5","1.16.5","v1.16.4","1.16.4","v1.16.3","1.16.3","v1.16.2","1.16.2","v1.16.1","1.16.1","v1.16.0","1.16.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-32793.json"}}],"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/32xxx/CVE-2025-32793.json"},{"type":"ADVISORY","url":"https://github.com/cilium/cilium/security/advisories/GHSA-5vxx-c285-pcq4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-32793"},{"type":"FIX","url":"https://github.com/cilium/cilium/pull/38592"}],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-319"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/32xxx/CVE-2025-32793.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N"}]}
